Abstract
The utility model provides a polyurethane plate which is characterized in that an arc grooves are formed at the middle of the two ends of the polyurethane plate respectively, an overlapped groove is formed at the two sides of the arc groove at one end of the polyurethane plate respectively, and an overlapped boss is arranged at the two sides of the arc groove at the other end of the polyurethane plate respectively and corresponds to the overlapped groove. When the polyurethane plate is overlapped, the overlapped grooves and the overlapped bosses are correspondingly aligned, a columnar cavity is formed at the middle of the polyurethane plate, liquid polyurethane is injected into the columnar cavity for solidification, so that the polyurethane plate has higher sealing performance, and energy sources are saved.
Description
Technical field
The utility model belongs to the polyurethane sheet field, especially relates to a kind of polyurethane sheet with new interface.
Background technology
In the freezer industry, generally use polyurethane thermal insulation board, and the overlap joint problem between polyurethane sheet is paid close attention to by people.Most polyurethane sheet bridging method is to adopt box and pin or eccentric hook and snap close overlap joint and the filling with sealant at the place, slit in existing technology.But under the low-down situation of temperature of ice house,, there is the difference of shrinkage ratio, causes technical problem poorly sealed between plate to occur, cause heat insulation effect to reduce and energy waste because fluid sealant and polyurethane are not same substances.
Summary of the invention
The problem that the utility model will solve provides a kind of novel overlap joint groove that has, and makes the better polyurethane sheet of sealing performance, especially is fit to the very low freezer of temperature requirement and uses.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: at the polyurethane sheet two ends; An arc groove is respectively established in the centre, and an overlap joint groove is respectively established in end arc groove both sides, other end arc groove both sides respectively establish one with overlap the corresponding overlap joint boss of groove.In polyurethane sheet when overlap joint,, boss is just in time corresponding agrees with for overlap joint groove and overlap joint, and middlely forms a column cavity, in the column cavity, is injecting liquid polyurethane, treats curing after overexpansion, cooling to make firm the snapping into together of polyurethane sheet.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the connection between polyurethane sheet is more tight, and better tightness is simple in structure, can reach the very low advantages such as refrigerator sealing requirements of temperature requirement.
Description of drawings
Fig. 1 is the sectional view at the utility model polyurethane sheet two ends
Among the figure:
1, polyurethane sheet 2, arc groove 3, overlap joint groove
4, overlap joint boss
The specific embodiment
Shown in Fig. 1 polyurethane sheet; The polyurethane sheet that the utility model adopted; Comprise polyurethane sheet 1, at the polyurethane sheet two ends, an arc groove 2 is respectively established in the centre position; An overlap joint groove 3 is respectively established in one end arc groove both sides, other end arc groove both sides respectively establish one with overlap the corresponding overlap joint boss 4 of groove.
The course of work of this instance: during the overlap joint polyurethane sheet, overlap groove and overlap boss and agree with, the arc groove of both sides forms a column cavity, in cavity, injects liquid polyurethane, curing after waiting to expand, cooling off.The effect of above-mentioned two structures makes the connection between polyurethane sheet tightr, and better tightness can reach the requirement of the very low refrigerator sealing of temperature requirement, thus energy conservation.
In the above-described embodiments, the corresponding overlap joint groove in two ends is trapezoidal with the overlap joint boss, equally also can replace with in square or the triangle any, other shapes that also can other those skilled in the art can expect.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (2)
1. polyurethane sheet; It is characterized in that: an arc groove is respectively established in the middle part at polyurethane sheet two ends; An overlap joint groove is respectively established in the arc groove both sides of an end therein, the arc groove both sides of the other end respectively establish one with overlap the corresponding overlap joint boss of groove.
2. polyurethane sheet according to claim 1 is characterized in that: the corresponding overlap joint groove in two ends and overlap joint boss can be in square, trapezoidal or the triangle any.
